2.1 Uncrating and Inspection

2.2 Installation

When the unit is received and while the carrier is still present, inspect the shipping carton for any damage that may have occurred in transit. If the carton is broken, torn, or punctured,

Figure 2-1 Machine bolted to Shipping Base

Figure 2-2 Installing Mounting Legs or Casters

CAUTION Be sure to properly support the machine when removing bolts and installing legs or casters.

CAUTION

All materials and connections must conform to local requirements and be in compliance with the National Electrical Code (NEC).

note the damage on the carrier’s freight bill and notify the carrier’s local agent immediately.

1. Remove the carton from the pallet, and move the machine as close as possible to the permanent location.

2. Remove the shipping bolts on the bottom of the freezer (figure 2-1) and install either the legs or casters (figure 2-

2).

NOTE: Screw

casters or legs all the way in coupling, then adjust out to level.

1. This freezer is designed for indoor use and must be protected from outdoor weather conditions.

2. Where codes permit, we recommend that the freezer be installed on casters and have flexible water and electrical connections for service and cleaning ability.

3. Air cooled models require a minimum 6 inch (15 cm) clearance on either the side panels or the rear panel for adequate ventilation. Freezers designed with top air discharge require at least 18 inches (45 cm) above the top panel be free of obstructions. Anything blocking ventilation of the freezer (including cone dispensers) will reduce the efficiency of the freezer.

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Always verify electrical specifications on the data plate of each freezer. Data plate specifications will always supersede the information in this manual.

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Check the data plate for fuse size, wire ampacity, and electrical specifications.

2. Refer to the wiring diagram provided for proper power connections.

4. Water cooled models will require a 3/8 inch MPT water inlet and water waste connection. The connections are found on the bottom under the compressor mounting area and are clearly tagged “Water Inlet” and “Water Waste.” A manual shut-off valve should be installed in the water inlet line at the time of installation. The water pressure must be between 35-140 psig (241-965 kPa) for proper operation.

5. Place the freezer in the final location and level by adjusting the legs or casters so that it is level side-to-side and the front is approximately ¼ inch (6 mm) lower than the rear to allow proper drainage of the freezing cylinder.

2. Supply voltage must be within +

10% of voltage indicated on the nameplate. Also, on three-phase systems, voltage between phases must be balanced within 2%. (More than a 6 volt difference between any two voltage measurements at 208-230 volts indicates a possible imbalance.) Request your local power company to correct any voltage problem.

3. An easily accessible main power

disconnect must be provided for all poles of the wiring to the freezer.

3. Electrical connections are made in the junction boxes located mid-level behind the left side panel.

4. Use a flexible connection when permissible. All materials and connections must conform to local codes and the National Electrical Code.

5. For 3 phase freezers, beater shaft rotation must be clockwise as viewed from the front of the freezer.

This control protects the beater motor against failure from an overload condition by automatically shutting down the freezer. To restart the freezer properly, turn the SELECTOR switch to “OFF” and wait 2-3 minutes. Then depress the red reset button and turn the SELECTOR switch back to the “AUTO” or “CLEAN” position.

When flashing, this light indicates the mix in the mix container is at a low level and should be refilled as soon as possible. Always maintain at least 2 inches (5 cm) of mix in the container. For best operating results keep container full.

For the “ADD MIX” indicator lights to work, the probes must be installed in the mix container, with cords attached and plugged

Important: If the overload trips frequently, your freezer should be checked for proper product temperature, overrun and voltage. Contact your Electro Freeze Distributor.

Important: If proper mix level is not maintained, a freeze-up may occur and cause damage to the freezer.

6.3 Cleaning Instructions

NOTE: It is your responsibility to be aware of, and conform to, the requirements for meeting all federal, state, and local laws concerning the frequency of cleaning and sanitizing the freezer.

1. Prepare a three-compartment sink for cleaning, rinsing, and sanitizing parts removed from the freezer, per applicable local health codes. Also prepare a clean surface to air-dry all parts.

Do not use unapproved sanitizer or laundry bleach. These materials may contain high concentrations of chlorine and will chemically attack freezer components.

Figure 6-5 Clean head ports and openings with brush.

CAUTION To prevent bacteria growth, remove all O-rings when cleaning. Failure to do so could create a health hazard.

 Important:

CAUTION Electrical shock hazard. Do not splash water on switches or allow water to flow onto electrical components inside the machine.

NOTE: The sanitizer should be mixed

according to the manufacturer’s instructions to yield 100PPM available chlorine solution (example: Stera-Sheen Green Label.) Use warm water (100° to 110°F or 38° to 43°C) to wash, rinse, and sanitize.

2. Wash all parts removed from the freezer thoroughly with dish detergent. Clean the following parts with the appropriate supplied brush:

a. The mix container, pickup

tube assemblies, hoses, and probes.

b. The head plunger openings, center plunger ports, O-ring grooves, dispense nozzle mounting rings, and mix ports, as shown in figure 6-5.

SEAL-ASSY SHAFT

Correct assembly of the freezer is essential to prevent leakage of the product and damage to the freezer. To assemble the freezer you will need an approved lubricant (such as Petrol-Gel). Make sure all parts of the assemblies have been washed and sanitized before assembling. Persons assembling the freezer must first wash and sanitize their hands and forearms with an approved sanitizer. Follow these directions for each cylinder of the freezer.

CAUTION To avoid electrical shock or contact with moving parts, make sure all switches are in the “OFF” position and that the main power supply is disconnected. Some freezers have more than one disconnect switch.

1. To assemble the shaft seal, install the cup seal and O-ring on the washer (see figure 7-1). Apply a light amount of approved sanitary lubricant (such as Petrol-Gel) to the O-ring and the face of the plastic washer opposite the bell portion of the seal. Do not allow any lubricant to come into contact with the bell-shaped rubber portion of the seals.

2. Install the shaft seal over the rear of the beater shaft, with the bellshaped portion facing the rear, as shown in figure 7-2.

3. Place the scraper blades on the beater shaft, making sure the blades are installed properly (see figure 7-3).

4. Insert the assembled beater shaft into the cylinder by placing the rear blade on the bottom of the cylinder. This will center the beater and allow alignment with the drive coupling. Rotate the beater assembly while pushing, until the shank has engaged the coupling. Repeat for second cylinder assembly.

5. (Refer to figure 7-4.) Install and then lubricate the O-rings on the dispensing plungers and insert all three halfway into the head.

6. Install and then lubricate the 4inch head O-rings.

7. Position the handle(s) in the head and ensure that the longest handle is in the center plunger. Lock in place with the handle pin.

8. Install and lubricate O-rings on the air bleed plugs. Insert plugs in the head assembly.

9. Lubricate the inside surface of the head bushing and place in the dispense head assembly by rotating until the bushing locks in place.

BLEED

 Important:

ALWAYS make sure the head bushing is positioned in the head. Operating the freezer with a missing or badly worn bushing will damage the beater and cylinder.

 Important:

Excessive force will damage the head. Do not use tools to tighten.

10. Install the dispensing head onto the freezer by aligning the studs with the holes in the head and sliding toward the freezer. Tighten the hand knobs evenly, finger-tight only.

11. Install the plunger rods. The nozzles will be installed on the mix outlet at the bottom of the dispense head after sanitizing.

8 Start-up Instructions

The washing and sanitizing instructions explained in this manual are important procedures to remove bacteria and maintain a clean, sanitary freezer. The soft serve freezer must be disassembled and washed according to the instructions in the manual. Always sanitize before start-up to ensure the best possible cleanliness.

Do not use unapproved sanitizers or laundry bleach. These materials may contain high concentrations of chlorine and will chemically attack freezer components.

Note: It is your responsibility to be aware of, and conform to, the requirements for meeting all local, state, and federal laws concerning the frequency of cleaning and sanitizing the freezer.

1. Prepare 2 gallons (7.5 liters) of sanitizing solution in each mix container. Sanitizing solution must be mixed according to manufacturer’s instructions to yield 100 PPM available chlorine solution (example: SteraSheen Green Label). Use warm water (100 to 110°F or 37 to 43°C) to wash, rinse, and sanitize.

Mix Transfer System will be pressurized during operation. Make sure all components and fasteners are secure before start-up.

CAUTION To prevent bacteria growth, use only approved sanitizers to sanitize the machine. Sanitizing must be done just prior to starting the machine. Failure to do so could create a health hazard.

 Important:

CAUTION

2. Wash and sanitize your hands

and forearms.

3. Clean the interior mix container walls, the underside of the container covers, and low mix probes (see figure 8-1 probe assembly only) with sanitizer solution and the appropriate brush provided.

4. Place the mix containers with sanitizer in the cabinet.

 Important:

Never let the sanitizer remain in the freezer for longer than 15 minutes.

5. Insert the pickup tubes into the sanitizer solution and sanitize the outside portion. If plastic mix bag systems are used, be sure all adaptors and items that will come into contact with mix are sanitized.

6. Place an empty container under the dispensing head.

7. Open the air bleed plugs by pulling up until the plugs touch the bottom of the switch box.

8. Reconnect the main power supply to the freezer. Turn the MTS switches to “ON”. This will push the sanitizer up into the cylinders.

9. When sanitizer flows out the bottom of the dispense head, close the air bleed plugs.

 Important:

DO NOT use the “AUTO” position with sanitizer in the cylinder. The freezer will be damaged.

9 Closing Procedures

9.1 Night Switch Operation

9.2 Draining Product

1. In areas where health codes will allow, the freezer may be switched to night operation that will allow the freezer to cycle all night and maintain approximately 38°F (3°C) or lower product in the cylinders and cabinet.

2. To switch the freezer to the night mode, leave the SELECTOR switches on “AUTO” and the cabinet switch “ON”.

3. Turn the MTS switches to the “OFF” position.

4. Turn the DAY/NIGHT switches to “NIGHT” and let the machine cycle.

To remove frozen product from the cylinders:

1. Place the SELECTOR switches

in the “CLEAN” position and the MTS switches in the “ON” position.

2. Let the beater shafts run for 5

minutes. This will allow the product in the cylinders to soften.

3. Place a clean, sanitized con-

tainer under the dispensing nozzles.

4. Remove the stainless steel

pickup tubes from the mix. Remove the mix containers and disconnect the low mix cords.

5. Very slowly dispense the semi-

frozen product until it quits dispensing.

6. Close plungers and turn the

MTS switches and cabinet switch to the “OFF” position. Place the pickup tubes into a container of cold water, turn the MTS switches to “ON”, and allow the MTS to fill and pressurize the cylinders with water.

5. Remove serrated nozzles and clean the drip tray assembly and all soiled surfaces with soap and water. Use the sanitizing solution in the spray bottle and the small brush to clean the bottom of the plunger openings

6. To start the machine after using the NIGHT mode, turn the DAY/NIGHT switches to “DAY” and the MTS switches to “ON”. Before replacing sanitized nozzles use a small brush and sanitizing solution to clean the bottom of the plunger openings.

7. Very slowly dispense the cold water. Follow with a container of warm water (100-110°F or 37-43°C) and repeat until the dispensed water is clear. Turn all switches to “OFF” and drain all water from the cylinders.

8. Prepare 2 gallons (7.5 liters) of sanitizing solution for each cylinder. Sanitizing solution must be mixed according to manufacturer’s instructions to yield 100 ppm available chlorine solution (example: Stera-Sheen Green Label).

9. Insert the pickup tubes into the sanitizer solution and close the plungers.

10. Open the air bleed plugs by pulling up until the plugs touch the bottom of the switch box. Set the MTS switches to the “ON” position. When sanitizer solution flows out the bottom of the head, close the plugs and allow cylinders to pressurize.

10 Soft Serve Information

10.1 Overrun

As mix is frozen in the freezing cylinder, air is incorporated into the mix to increase its volume, as well as enhance the taste and texture of the finished product. The increase in volume is called overrun. Fifty percent overrun means a volume increase of 50% — 10 gallons of liquid mix has become 15 gallons of finished product.

Controlled overrun is important to maintain consistency in product quality. Too much overrun (air) results in a light, fluffy product lacking the cold, refreshing appeal of a quality product. Too little overrun results in a wet, heavy product.

To correctly measure the overrun, perform the following steps:

a. Place an empty pint container on the scale* and adjust your scale to zero.

b. Remove container from scale and fill with liquid product to the top. Weigh container and record.

c. Replace liquid product with frozen product, being sure to leave no

voids or air spaces in the container.

d. Strike off the excess product so it is even with the top of the container and measure the weight.

e. Use the following formula to figure overrun percentage:

“Weight of liquid mix minus weight of frozen product/divided by the frozen weight.” See example below:

Weight of pint of liquid mix = 18 oz.

Weight of pint =

12 oz.

of frozen product

Difference = 6 oz.

6 oz. divided by 12 oz. = .5

.5 x 100 = 50% overrun

* Your Electro Freeze Distributor can provide a scale (P/N 158049) that is graduated in overrun percentage.

10.2 Overrun Adjustment

23456789012345

184833

NOTE: Each person who operates the freezer should know what overrun is and how to calculate it.

Overrun is regulated by the air meter. You were supplied with three air meters, each having a different size orifice. The smaller the hole and number, the lower the overrun. The larger the hole and number, the higher the overrun. Each half-size change of the air meter number will change the overrun 3 to 5%. Each full size change of the air meter number will change the overrun 8-10%. The orifice in this air meter must be open at all times. It is the only source of air into the freezing cylinder. Check this daily!

Figure 10-1 Air Meter

The mix will be a factor in determining the amount of overrun you will be able to achieve. Some mixes will accept more air than others, thus affecting the size of air meter you can use. Test to see which air meter will give you the best overrun and the best product. Run each air meter for a few hours until you decide.

You may have a slightly higher overrun when you first start up the machine. After the machine has run long enough to dispense at least one full cylinder of product, you will have the overrun that the machine will hold the remainder of the day. Contact your mix supplier for the recommended amount of overrun for each product used.

11 Routine Maintenance

Electro Freeze recommends the following schedule to help maintain your Model 88TN-CMT Soft Serve Twist Freezer in like-new operating condition. Take the time to learn and perform these routine procedures and receive in return many years of valuable service from your freezer. Protect your investment!

DAILY

1. Disassemble, wash, rinse, sanitize, and air-dry all parts that come into contact with the mix or product.

CAUTION To prevent bacteria growth, remove all O-rings when cleaning. Failure to do so could create a health hazard.

2. Clean the cylinder and drain tube

with the appropriate brushes.

3. When cleaning, inspect all orings, seals and hoses. Replace any o-ring, seal or hose that is worn, torn, or loose fitting.

4. Wipe all exterior surfaces of the freezer to remove any splattered mix.

5. Check overrun and temperature of the product.

AS NEEDED

CAUTION To avoid electrical shock or contact with moving parts, make sure all switches are in the “OFF” position and that the main power supply is disconnected. Some freezers have more than one disconnect switch.

1. Clean the Mix Transfer System:

Important: If the transfer hose is assembled improperly or replacement has been neglected, it may be necessary to clean mix from the MTS due to hose failure.

If this happens frequently the MTS should be removed for complete cleaning.

A. Test Head Switch.

The head switch feature is designed to prevent the beater shaft from being accidentally activated. It is essential that the proper operation of this switch be verified on a routine basis. Use the following instructions to test for proper operation:

1. Be sure all switches are in the

“OFF” position.

2. Disconnect the main power

supply.

3. Remove the dispense head and

beater shaft assembly.

4. Connect the main power supply.

CAUTION Moving parts. DO NOT place hands in the freezing cylinder. Severe personal injury could result.

5. Turn the selector switch to the

“CLEAN” position.

6. Look inside the freezing cylinder toward the rear—the drive shaft coupling should NOT be turning. Turn the switch off and disconnect the main power supply.

7. If the drive shaft coupling is turning, or you are unable to determine whether or not the shaft is turning, turn the switch to the “OFF” position, disconnect the main power supply and contact your Electro Freeze distributor for service. DO NOT place the freezer in service until the problem has been fixed.

MONTHLY

B. Water Condenser.

Check the outlet water temperature of water-cooled condensers at the floor drain. Ideal water temperatures should be about 95°F (35°C) with a 70°F (21.1°C) water inlet temperature.

C. Test MTS Slide Switch.

The MTS slide switch feature is designed to prevent the MTS gear motor from being accidentally activated. It is essential that the proper operation of this switch be verified on a routine basis. Use the following instructions to test for proper operation:

CAUTION Make sure system is depressurized before proceeding.

1. Be sure all switches are in the “OFF”

position.

2. Pull down MTS handle to open the

housing.

3. Turn MTS switch to “ON”.

CAUTION DO NOT place hands near the MTS rollers. Severe personal injury could result.

This instruction sheet is not intended to be used in place of the Operator’s Manual. Use the following information to assist you only after you have read, understood, and are accomplished in the procedures for cleaning and sanitizing detailed in the Electro Freeze freezer Operator’s Manual.

DRAINING PRODUCT

Follow Closing Procedures in Operator’s Manual to remove frozen product from the freezer.

1. Turn selector switches to “CLEAN”, MTS switches to “ON”, CAB switch to “OFF”.

2. Empty the remaining mix out of mix containers.

3. Run beaters 5 minutes to soften product. Dispense as much frozen product as possible.

4. Pour 2 gallons of cool water into each mix container, allowing the cylinders to fill with water.

5. Open plungers to drain mix and water. Repeat step 4 until water is clear.

6. Prepare and pour 2 gallons of warm sanitizing solution of 100ppm available chlorine in container.

7. Open air relief and fill each cylinder with sanitizer. Close air relief. Place selector switch to clean for 5 minutes.

8. Put all switches in the “OFF” position. Drain completely.

DISASSEMBLY

CAUTION: To avoid electrical shock or contact with moving parts, make sure all switches are in the “OFF” position and that the main power supply is disconnected. Some freezers have more than one disconnect switch.

CAUTION: PRESSURIZED SYSTEM. Plungers must be open before disassembly.

Disassemble the freezer components in accordance with the Operator’s Manual instructions.

ASSEMBLY

Assemble and lubricate freezer components in accordance with the Operator’s Manual instructions.

1. Remove dispensing head and beater shafts from freezer.

Disassemble MTS and move to cleaning area.

CLEANING

1. Prepare a three-compartment sink for cleaning, rinsing, and

sanitizing parts removed from the freezer per applicable health codes. The sanitizer should be mixed according to the manufacturer’s instructions to yield 100 parts per million (PPM) available chlorine solution. (example: Stera-Sheen Green Label).

2. Disassemble all parts and remove o-rings. Clean each part with

the appropriate brush supplied with freezer.

3. Wash, rinse, sanitize, and air dry all parts removed from the

freezer. For proper sanitizing, the parts must remain in the sanitizer for 5 minutes.

4. Go to freezer and use sanitizing solution to thoroughly brush the

mix feed tubes from the refrigerated cabinet to the cylinders.

5. Brush the inside of the cylinders with sanitizing solution, making

certain to clean the back walls.

6. Brush the inside of the drain tube.

SANITIZING

1. Wash and sanitize your hands and forearms.

2. Prepare 2 gallons (7.5 liters) of sanitizing solution in each mix container. Sanitizing solution must be mixed according to manufacturer’s instructions to yield 100 PPM (parts per million) available chlorine solution.

3. Brush the interior mix container walls, the underside of the container covers, and low mix probes with sanitizer solution.

4. Place the mix containers with sanitizer in the refrigerated cabinet, insert pickup tube and sanitize exterior of the tubes.

5. Place an empty container under the dispensing head.

6. Open the air bleed plugs by pulling up until the plugs touch the bottom of the switch box.

7. Reconnect the main power supply to the freezer. Turn the MTS switches to “ON”. This will push the sanitizer into the cylinders.

8. When sanitizer flows out the bottom of the dispense head, close the air bleed plugs.

SANITIZING (continued)

9. Turn both selector switches to “CLEAN” and allow the beaters to run for 5 minutes. Check for leaks around the head, drain tube, clamps and MTS.

10. Drain the solution from the cylinders by slowly pulling down on the dispense handles. NOTE: Some sanitizer

will remain in hoses and cylinders.

11. Leave the handles down, and turn the selector switches to “OFF”. Let the MTS force all possible sanitizer out of the freezing cylinders.

Important:

Failure to completely remove sanitizer or water

from the freezing cylinder before placing in “AUTO” will damage the freezer.

12. Turn the MTS switches to “OFF”.

13. Remove the mix inlet tubes, holding the top 6-inch portion only.

14. Remove the mix containers and empty any remaining sanitizer.

Priming The Freezer

1. Make sure that your hands, forearms, and all freezer assemblies are sanitized.

Priming The Freezer

(continued)

6. Place an empty container under the dispensing head on the drip tray.

7. Open the side plungers and air bleed plugs.

8. Turn the MTS switches to “ON” and allow the mix to push the remaining sanitizer from the cylinders through the plunger openings.

2. Holding the top 6-inch portion only, insert the pickup tubes into the sanitized mix container through the small hole in the rear cover and set containers in the cabinet.

3. Fill the mix containers with mix and install the front covers.

4. Insert the low mix probes through the large hole in the rear cover, and connect the probe cords to the probes and to the back of the cabinet.

5. Turn the cabinet switch to “ON” and close the cabinet door.

9. Close the side plungers when pure mix is coming out.

Important: Failure to completely remove sanitizer or water from the freezing cylinder before placing in “AUTO” will damage the freezer.

10. After mix appears at the bottom of the head (approximately 50–55 seconds), close the air bleed plugs and wait for the MTS to fill the cylinders and shut off.

11. After the MTS has cycled off (approximately 30 seconds) turn both selector switches to “AUTO”, both DAY/NIGHT switches to “DAY”, and both MTS switches to “ON”.

12. Allow the freezer to cycle for 15 minutes. Sanitize the nozzles and install on the head. The product is now ready to serve.
